[slurm-users] Creating priority quotas

QOS is probably the right way to go. You can set up a QOS 'vip', which
can preempt other QOS. We don't preempt, but use multifactor priority
with various QOS with different priority values. In that case, VIP jobs
won't start immediately, but just get pushed to the front of the queue.
On the other hand, no CPU-time is lost due to low-status jobs being
terminated early due to preemption (although if the low-status jobs are
able to do some form of checkpointing that will be less of an issue).
Depending on how pushy your VIPs are, they might go for a preemptionless
